Microsoft takes $550 off the Alienware 15 gaming laptop as time runs out on PC deals, Microsoft’s 12 Days of Deals has produced some amazing PC sales, and Microsoft is spotlighting one more: the rugged, powerful Alienware 15 R3 gaming notebook, a bargain at $550 off—and with the opportunity to save $100 more.

Microsoft’s 12 Days of Deals sales have produced some epic bargains, notably the $550 off the Dell XPS 13 steal that has, sadly, expired. But smart shoppers know the power of last-minute deals, and there’s still a few to be scored as Microsoft’s deals days expire.

To be fair, many of these deals appeared earlier in the week—last Tuesday, specifically. About 100 or so deals were available. Now we’re down to about 60 or so, but some good bargains are still ripe for the plucking. (Microsoft still seems to be advertising free shipping, too.)

The one that stands out is the $1,599 Alienware 15 R3 deal, a 4-star gaming laptop that PCWorld reviewed just over a week ago. Unbelievably, that 15.6-inch laptop was priced at $1,996 then (MSRP $2,149), and has since plunged another $400. It’s a massive, rugged laptop, more suited to plopping on a desk than your lap. But with a 7th-gen Core i7, 16GB of RAM, 256GB SSD/1TB HDD and an Nvidia GeForce GTX 1070 graphics chip inside, it’s made for gaming.

We’ve been a bit dubious of Microsoft’s Windows Mixed Reality headsets, but if you’re interested in picking one up, Microsoft says you can save $100 more with a bundle. (The unnecessarily convoluted process involves knocking $50 more of the price of the Alienware 15 and $50 off the headset.)

If the Alienware 15 is a bit small for your tastes, you can try the Alienware 17 R4 AW17R4-7004SLV-PUS for $1,899 ($600 discount). Though this discount isn’t as steep as Microsoft claims, it’s still a solid deal for the Alienware 17 R4, PCWorld’s favorite 17-inch gaming laptop.

The remaining offers are hit and miss, with $100 to $150 off here and there. Unfortunately, discounts of this magnitude represent a gray area between the MSRP, the “actual” price of the hardware, and a viable discount. They’re often too close to call.

Microsoft’s 12 Days of Deals are essentially done, though Microsoft is releasing one more, just for gamers, on Sunday: an Xbox One S (normally $229 with a game or two) for $199, complete with your choice of a bundled game.
